TOILET SEAT AND COVER HINGE Filed Dec. 19, 1941 2 Sheets-Sheet 2 I! will? I II IL- Patented Jan. 9, 1945 UNITED STATES PATENT OFFICE TOILET sEA'r AND coves HINGE Harold D. Watsn, Beloit, Wis. Application December 19, 1941, Serial N0. 423,569 4 Claims. (ci -2361f This invention relates to toilet seat and cover hinges.

It is an object of this invention to provide a hinge construction suitable for toilet seats and covers which is formed entirely, of plastic material so as to lend itself more readily toiharrnonious color combinations and to obviate the unsightly corrosion which is inevitable where the hinge parts are made of metal.

An additional object of this invention seats and covers inwhich the seat and covercarried hinge parts are provided with integral trunnions received in bearing sockets formed in the supporting standards or pedestals on the bowl. l r i A further object of this invention is to provide a hinge construction of the character described which isdesigned to relievethe trunnions ofthe hinges of substantially all "strain incidental to the application of weight onto the lowered seat and cover, and toeliminate shearin stresses on any part ofthe hinge structure.

6 With the above and other objects in View which will appear as the description proceeds, thisinvention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described-and more particularly defined by the appended claims, it being understood that such changes in the preciseembodiment of the herein disclosed invention may be made as come within the scope of the claims.

The accompanying drawings illustrate several complete examples of the physicalembodiments @of the invention constructed in accordancewith the best modes so far devised forthe practical application of the principles thereof, and in which: 1

Figure 1 is-a top plan view of a hingecon struction embodying this invention, a part thereof being broken away and in section;

Figure 2 is a cross-sectional through Figure 1 onthe plane of the line 2-2;

Figure 3 is a cross-sectional viewtaken through Figure 1 on the plane of the line 33;;

Figure 4 is a plan view similar to Figurelil- 1 lustrating a modified form of the invention; and

Figure 5 is a cross-sectionalview taken through Figure 4 on the plane of the line 5----5.

Referring now particularly to. the accompanying drawings, in which. like numerals indicate like parts, the numeral 3 designates the bowl of a toilet providedwith the conventional seat 5 and cover I.

Thehinge construction of this invention conis to provide an improved hingeconstruction fortoilet,

view takensists of a pair of spaced similar. but opposite bearingstandards a cover hinge member 34 and apairof seat hinge members 39.

Allof these parts are formed of plastic material so that they may be provided in colors to match anyidesired color scheme. The use of plastic material also overcomes the objectionable discoloration caused by corrosion to which metal hinge parts are: subject.

The bearing standards are secured to the top surface ll: of the bowl at. the customary location of the hinge by means of studs l2 embedded in the bearing standards and passing through holes in the flange of the bowl to have nuts (not shown) threaded thereon and drawn up against the undersurface of the flange.

These bearing standards asstated are similar and opposite. They haverelatively flat inner faces 3| opposedto each other and flat outer faces ,32 substantially parallel with the inner "faces, said inner and outer faces extending perpendicularly from the top surface I I of the bowl. Bearing sockets 33 enter the body of each of the standards from both theirinner and outer faces and are all in line with each otherso that r they lie on a common horizontal axis extending transversely across the rear of the bowl, the

sockets of each standards preferably being the oppositeends of transverse bores.

Thecover hinge member34is provided with a flat attaching portion 35 which is secured to the underside of the cover by screws or other fastening means and has an armfifi directed angularly rearwardly. from the attaching portion to extend a. short distance downwardly therefrom in the. lowered position of the cover.

The cover hinge member 34 extends across the full distance between thebearing standards and to the bearing standards comprises a pair of has integral trunnions 31 projectingin opposite directions, from the extremities of its arm 36 which. are pivotally received in the bearing sockets 33openingto the inner faces of the hearing standards; 6

Projecting upwardly from the cover side of the fiat attaching portion is an abutment or rib 38.

integral therewith which is engageable with the rear edge of the cover andthus serves to facilitate locating the cover hinge member in its attachment tothe cover. l i i The means for pivotally connecting the seat 1 seat hinge members 39 one adjacent to the outer face of each bearing standardlandhaving flat attachingportions 4|] isecured to the underside of the seat in any suitable manner.

These seat hinge members each have an arm 4| directed angularly from the attaching portion thereof in a direction to project substantially perpendicularly upwardly toward the hinge axis when the seat is in lowered position. Integral trunnions 42 project from these arms toward each other and their adjacent bearing standards to be received in the bearing sockets opening to the outer faces thereof.

When the-seat is-lin its lowered, positiontshown in Figure -2, we ightimparted to the (seat issupported in such a mannerthat the trunnions of the seat hinge members are relieved of all strain or shearing stress. This desirable result is achieved through the provision of pads or bosses 83 projecting outwardly from the zoutersfaces of the bearing standards and resting on the top face H of the bowl.

These pads or bosses are positioned tolbe enobtained which'rallows zthe: hingermembers: to the formed entirely of zplasticcmaterial. J

If desired, it the v1 trunnions uof ""the lzcover z-shinge member mayxiabe "relieved fofwistrain incidental 1110 the application 'of weight :ont'the1covers'as: illustrated in Figures =4 --and-5, linclusive, :by having portions-45 on the 'cover hingel'member adjacent to its trunnions "engage on the :.vtop"2surfaces ztof ledges 6 projecting! fromLthe1- inner Jfia'ces 'rof :the bearing standardsx3ll.

As' best seen in: Figure v=5,' .the porti'ons fiaon "the cover hinge member are *fiforme'd integral 1' with the arm 36- thereof L and extend zonlyza sh'ortrdistance below the arm-in the lowered position tof the cover. The: pads or ledgesMB. on ithe inner surfaces of'the bearingstandards'are integral with the standards and rest-directly on the top face it of thesbowl. These pads extend up- 'wardly along the inner sides "of the bearing standards to 'points'adjacent to the bottom f the arm 36 and consequently.close tozthe hinge axis to be engaged fiatwise by the portions 45 on the cover hinge memberin aplane paralll to the supporting surface and'fisu-bstantially v directly beneath the hinge axis.

. :Thus it will be readilyiappreciated that' weight applied to the cover is supportediby.the' ledges or pads 46 on the-bearing'standards which :are

placed in compression between-rthe portions 45 gaged by the seats hinge members at areas sfibstantially l'directlyxbeneathitheihinge axis :of rthe rib projecting angularly from the rear edge portion of the flange and extending for the entire length of s'aidrearedge, and coaxial trunnions projecting from the end of the rib; a pair of standards each consisting of one integral molding having asubstantially flat bottom and an anchor bolt embedded therein and projecting from the bottom thereof, the upper portion of the standard having substantially parallel flat inner eandtoutereside portionsand coaxial truninion: sockets :opening "to .said :side portions; the trunnions on the cover hinge member being re- \eeived in the sockets opening to the inner sides on the coverhinge arm'and the top face ll of the bowl; and that no strains orshearing "stresses are imparted to the trunnions of=either the :cover hinge member or the'seatxhinge member. v

From the foregoingvdescriptionrtaken in connection with the accompanying drawings, it :will be readily apparent that the novel'idesign'aofthe hinge construction of this invention makes .the use of plastic material entirely practical .'.and feasible so that all the advantageswhich attend the use of this new material may be fully realized.
